CAUTION!
Headphones can produce volume levels which may be hazardous
to your health. So before you put on your headphones, always
check that the selected volume level is not too high.
More information about the permissible exposure times depending on the
sound pressure level (dBA) based on the German Lärm- und Vibrations-
Arbeitsschutzverordnung (LärmVibrationsArbSchV) [Noise and Vibrations
Occupational Safety and Health Directive] can be found on page 39.

nector. Headphone models with a smaller jack plug (3.5 or 2.5 mm) can also
be connected using an adapter. Suitable adapters are available at specialist
retailers. The two headphone outputs may be used to drive two headphones in
parallel mode, preferably of the same type if possible. Whenever a headphone
is plugged into the left jack socket, the pre-out on the rear panel will be muted
(mute function).
CAUTION !
With active loudspeakers or power amplifiers connected to
the pre-out of the Linear D, make sure the volume control is
turned fully counterclockwise before pulling a plug out of this
headphone output.
3 | Volume control
Using the volume control you can adjust the output level of both the pre-out
and the headphone outputs. Turn the volume control counterclockwise to lower
the volume; turning it clockwise will increase the level.
We suggest you turn this control fully counterclockwise at the end of operation,
thus setting the output level to zero.
